On a question of style, Gaelic traditionally likes to put things in a sentence in a certain order, with the least important coming last. Funnily enough, this normally means blablabla [place] [time]. So traditionally, the "ideal" format of a sentence like the above would be

tha mi air an eilean sgìtheanach an-dràsta.

And before anyone crucifies me, this is not a rule cast in iron, even in the Gaelic of a hundred years back. But certainly a strong preference or tendency. And yes, English messes that up big time these days.

This is still the default position in standard English too - all other things being equal. If something is being stressed, it gets moved to the front (and/or voice stress, not such a Gaelic technique, kicks in). Colloquially, yes, there's more drift.

It's difficult to feel you are "on" an island with thousand-metre crags overlooking you! The usual in Gaelic is literally "in" an island, hence "anns an Eilean Sgitheanach" an àite "air an Eilean Sgitheanach".
